I would make an RA print of the neg, then judge. First of all, you have posted a severe crop. Second of all, you have scanned it, which is no way to flatter a C-41 film. Third of all, we don't know if it was scanned and processed well. Fourth of all, it could have been overexposed, and/or processed in foul chemicals, which would increase the graininess.
Reala is the best looking C-41 film made, IMO. I am thrilled to tears that I discovered a [somewhat] local source for it in 120 format. If only they made it in 4x5. From 35mm, this film is tack sharp at 8x12. For what it's worth, even Press 800 makes a decent 12x18 in my experience.
